I'm working with a domain controller (WS 2012 R2) and several client machines (all Win7). I'd like to add a group called Support to the Remote Desktop Users group on every client machine. From looking around, it appears that this is not possible. I've tried PSEXEC
(SysInternals) with mixed results (of the 2 machines I tried, I was only able to connect to one).
How can I add a user group to the Remote Desktop Users group on all machines connected to my domain controller? Doing it one by one is a lot of work.
You should be able to do this directly via Group Policy:
Add Group
This way you can even have separated support groups for different OUs.
Group Policy Preferences - group membership.
--- Edit ---
Please feel free to fill in the gaps. Group Policy is a core function of Active Directory domains. Group Policy Preferences are an extension introduced with Win2k8/Vista that can be used to control things such as files, groups, [temporary] registry keys/values on your clients. Try Googling "Group Policy Preferences" and read some of the MS how-to documents. The topic is too large for a meaningful answer here.
